APPARATUS FOR WETTING EMERY-WHEELS.

SPECIFICATION forming part of Letters Patent No. 707,420, dated August19, 1902.

Application filed July 31, 1901. Serial No. 70,385- (No model.)

To all whom it may concern:

Be it known that I, ELWIN R. HYDE, a citizen of the United States,residing at Bridgeport, county of Fairfield, State of Connectiout, haveinvented a new and useful Apparatus for 'lVetting Emery-Vheels, of whichthe following is a specification.

My invention relates to the class of grinding-machines in which it isrequired thatthe grinding-surface of the wheel, more especially anemery-wheel, be kept moistened, but at the same time desirable that aslittle water as possible be picked up by the wheel. It is thereforedesirable in this class of machines that the water in the tank bemaintained at such a height that the lower edge only of the wheel willjust touch the surface of the water, or at most be but slightly immersedtherein.

My invention therefore has for its object to provide a simple,inexpensive, and easily-operated apparatus adapted to all ordinarystyles of grinding machines, by means of which the water in the tank mayby an occasional slight operation be maintained at any desired height inthe tank-that is to say, slight attention to the machine and occasionalaction by the operator enables him to make good the loss of water fromthe tank through waste and evaporation.

With this end in view I have devised the novel grinding-wheel-wettingapparatus, of which the following description, in connection with theaccompanying drawing, is a specification, reference charactersbeing usedto designate the several parts.

The drawing is an elevation, partly broken away, to illustrate theconstruction and operation of my novel apparatus.

Adenotes an emery or othergrinding-wheel, whose shaft 13 is journaled ina suitable frame or casing C, which may be of any ordinary or preferredconstruction,necessarily, however, embodying a water-tank D. Thegrinding-wheel is ordinarily partly covered by a hood E, and a pan F isprovided to catch any water that may be thrown outside of the hood.

My invention consists in providing a waterreservoir G, which in order toprovide the l greatest capacity without its being in the way to theslightest extent and Without changing the design of the frame or casingIplace under the tank.

(ldenotes the normal water-line in the tank, and H a pipe extending fromnear the bottom of the reservoir to approximately the normal water-linein the tank. In practice the frame or casing may have cast therein ahorizontal Wall J to separate the tank of the reservoir, and pipe 11 maybecast into this wall.

K denotes an air-pump, which may be conveniently placed, as upon abracket L, cast integral with or rigidly secured to the frame. A pipe Mextends from this air-pump into the reservoir at the top. A petcock N isprovided in this pipe in order that air-pressure in the reservoir may bemaintained should it be necessary to disconnect the air-pump.

0 denotes a faucet, which is provided in order to permit drainage andcleaning of the tank should it become necessary.

The air-pump may be of any ordinary or preferred construction, it beingof course contemplated that the air-pump contain the usual valves toprevent the return of air. No pump need be described in detail, as thespecial pump used is not of the essence of my invention.

It will be obvious that by forcing air into the reservoir water will bedisplaced therein and will pass through pipe H to the tank, the operatorbeing simply required When the Water in the tank drops down low enoughso that the wheel will not be sufficiently wetted to operate the pumpslightly and force sufficient water from the reservoir into the tank toraise the water therein to the desired height, it being obvious alsothat the water in the tank may be raised as high as may be desired bycontinuing the pumping operation. In order to fill the reservoir, theoperator pours water into the pan, which passes to the tank and downpipe 11 into the reservoir. As soon as the reservoir is filled the waterwill of course rise above the normal waterline in the tank. Anysurplusage of water in the tank, however, may be removed at any time bymeans of the faucet.

Having thus described my invention, I in the tank by displacing water inthe resero1ai1n-- voir. to
